PATCH-APPLYING IEEGHANESM FOR- WINDOW ENVELOPES.

Application filed December 3, 1921.

To all whom it may concern Be it known that I, HARRY RADZINSKY, a citizen of the United States, and resident of the city, county, and State of New York,

have invented a certain new and useful Improvement in Patch-Applying Mechanism for Vindow Envelopes, of which the followin'g is a specification.

This invention relates to a machine for manufacturing the well known type of envelope known as the outlook or window en-v velope, wherein an opening is formed in the body of the envelope blank and a strip of transparent paper or like material is secured 1 over the opening so that the address, which is placed on the enclosure in such a manner as to register with the opening, can readily be seen through the transparent strip placed over the opening.

This machine relates to the means for applying thin transparent strips to the envelope blanks and over the opening therein and the object of this invention is to simplify the mechanism for applying said strips and to produce a patch-applying mechanism which will work with great speed and eliminate various objectionable features found in the present machines of this character.

These and other objects are accomplished by my invention, a more particular description of which will appear below.

Reference is to be had to the accompanying drawing forming a part hereof in which- Figure l is a side elevation of the portion of my improved machine for igumming the envelope blanks and also showing the patchapplying mechanism.

Figure 2 is a plan view of those portions of the machine which show the blank folding mechanism, patch-applying mechanism; the mechanism which delivers the patches to the patch-applying mechanism and the 5 mechanism which delivers the blank in position to receive the patch.

Figure 3 is a view of the portions of the machine used for removing patches from the Serial No. 519,716.

pile and transporting the same successively to the patch carrier which applies them to the envelope blanks.

Figures 4, 5, 6, 7 and 8 are diagrammatic views showing the method of operation of the creasing plunger and patchapplying member.

Throughout the various views of the draw ings, similar reference characters designate similar parts.

In the embodiment of my invention as I have shown it herein, I have not embodied many of the features of construction peculiar to machines for making envelopes as they are well understood and need no specific description here for the purpose of making my invention clear.

In Figure 1, I have shown a pile of blanks 1 placed upon a suitable support 2. Vertically movable above the pile of blanks are the gumming dies 3, 4, and 5 which are supported by a head 6 carried upon a rod 7. The rod is vertically movable in bearings 8 on the frame 9, suitable mechanism for producing such movement being utilized.

ounted to move back and forth below the gumming dies 3, 4 and 5 are suitable gumapplying rollers 10 which supply gum to the dies 3, 4 and 5 so that when said dies on their downward movement contact with the uppermost blank upon the pile 1, they apply the rows of gum indicated at 12, 13 and 14 to said blank. The row of gum 13 is applied by the central die 4 and said row of gum is located about the elongated opening 14" which is placed in the blank 15 and over which the transparent patch is applied. 85 As the gumming dies 3, 4 and 5 move upward they carry the blank with them and said blank is brought into contact with a plate 16 which strips the blank from the dies and causes said blank to drop down and no thus be deposited upon a conveyor formed of a pair of arms 17. These arms are provided attheir ends with hooks 18 so that the gummed blank cannot inadvertently slide off. The arms 17 are mounted to slide in guide-ways'lQ formed in the upper plate cross rod 22 and on said rod is mounted an arm 23 which receives a lever 24 extending from suitable mechanism for reciprocating the conveyor arms 17.

By means of themechanism above described, it will be understood that the gumming dies apply gum to successive blanks and lift said blanks to deposit the same upon the conveyor arms 17 as shown in Figure 2. Movement of said conveyor arms causes the blank to be carried by them to a position below suitable mechanism which folds the blank and'causes an application of the patch thereto. The plate 20 is provided with an opening 25 and this opening is located in that portion of the plate 20 which forms the creasing plate. creasing plunger 26 is located directly above the opening 25 which is adapted to force successive blanks through said opening, causing said blanks to be creased and finally carried down to a bed plate 27, which is surrounded by the usual mechanism for folding down the flaps of the envelope, and which completes the envelope. v

The frame 9 is provided with. guides 28 which carry a rod 29. This rod 29 is secured at its lower end to the creasing plunger 26. Adjacent its lower end the rod 29 is disclosed as being offset. The rod 29 is adapted to be reciprocated vertically in the guides 28, thus giving its attached creasing plunger 26 vertical movement. The rod 29 carries a projection 30 to which is pivoted a link 31, said link bein pivoted to a lever 32 leading to an appropriate part of the machine, which, through its operation, will rise and cause the rod 29 to be raised and lowered in synchronism with the other movements heretofore described.

75K plan view of the plunger is disclosed in Figure 2 where it will be seen that said plunger 26 is provided with an elongated opening extending through it, through which the patch-applying member 34 is adapted to carry a patch as will be hereinafter set forth. I

The patch-applying member 34 acts as a patch carrier for single successive patches and carries the same to the point where they are applied as will be set forth hereinafter.

The patch-applying member consists of a hollow plate 34 having an air chamber 35 and a plurality of ports 36 leading from said air chamber through the under face of the patch-applying member. The patch-applying member 34 corresponds in outline to the opening 33 in the creasing plunger and is movable therethrough. At 87 is shown a recess in the under side of the patch-applying member 34 in which a patch 88 is adapted to be held by suction. At 39 is shown a boss on the patchapplying member 34 and secured in said boss and extending upward therefrom is a tubular rod 40 which is vertically reciprocated in the guides 28 independently of the creasing plunger 26. T 0 reciprocate said rod 40 and consequently the patch-applying member 34 carried thereby, said tubular rod 40 is connected to a link 41 which is pivotally connected to an arm 42 secured on a cross shaft 43, on which is secured another arm 44, which has its end connected to a lever 45 extending to suitable cam mechanism which acts, through the medium of the mechanism just described, to vertically reciprocate the patchapplying member.

The rod 40 being tubular provides a con tinuous air passage 46 through which suction may be exerted, said suction being exerted by a pump or the like (not shown) and connected to the rod 40 by a flexible tube 47, a portion of which is disclosed in Figure 1, such connection in no way interfering with the reciprocating movement of the patch-applying member 34.

The initial positions of the patch-applying member 34 and the creasing plunger 26 are disclosed in Figure 1, wherein the parts are indicated at their highest point of ascent, or in their raised position, with the patchapplying member 34 located above the creasing plunger 26 and in position to receive and maintain a patch in the recess 37 on its under face. The means for supplying suc cessive single patches to the patch applying member 34 will now be described.

At 48 is the patch table or support which receives and holds a pile 49 of the thin transparent patches within a cage 50 secured on the table. The cage 50 is provided with an upright 51 in which is pivoted a tubular picker rod 52 having a laterally bent end 53 provided with a pair of downwardly extending nipples 54 through which suction is exerted to lift successive patches from the pile 49. As shown in Figure 2, the laterally bent end of the picker extends cross-wise of the patches and is located adjacent one end of the patch pile 49 and near the patch gripper which receives and supplies the suc lgessive patches to the patch applying mem- The rear end of the picker 52 is supported 011 a grooved pulley 55 which is slidably mounted on a shaft 56. This shaft is secured to and extends from one end of a rocker arm 57 pivoted in a bracket 58 fixed to a part of the machine. The outer end of the rocker arm is connected to suitable operating mechanism which acts to raise the laterally bent end 53 of the picker with a patch adhering thereto as disclosed in Figure 3. The raised patch is gripped by a pair of gripping fingers 59 and 60 and brought to the patch applying member 34 for application to a blank. 0n its way to the patch-applying member, the patch 33 is aligned by movement through pairs of aligning guides 61.

A red 64 extends across the machine and is fixedly held in supporting brackets 71 and 74. Mounted to slide-upon said rod is a sleeve 63 and the sliding movement of said sleeve on the rod iseflzected by means of a link 65 which has its end connected to a lever 66 that is actuated by suitable cam mechanism not shown. I l i y The sleeve 63 is provided with an arm or projection 62 which carries a rod 7 5 adapted to turn in the arm and upon which is mounted a spring 72, one end of the spring being secured to the arm 62 and the other end to the rod. This spring is adapted to close the upper grip-per member 59 which is secured upon the end of the rod 75, down upon the lower or fixed gripper member 60. The lower or fixed gripper member 60 is secured to a portion of the arm 62.

The opening and closing of the grippers 59 and 60 is effected by means of a tripper member 67 secured upon the end of the rod and having a roller 68 mounted upon its free end, and a dog 69. At 70 is a stop secured in the bracket 71 and said stop is adapted to contact with the dog 67 to pivot said dog out of the way to permit the grippers to close on a lifted patch, such closing of the grippers being effected by a spring 72 which brings a movable gripper 59 down on the stationary gripper 60 so that they grip the patch between them. 7

The grip-pers with the patch held between them then move across the machine carrying the patch between the plunger 26 and the patch-applying member 34 until they reach a point directly below the patch applying member 34 and above the creasing plunger 26. Suction being exerted through the patch applying member 34 causes the patch to adhere to its under surface and rest within the recess 37 provided therein for its reception. The grippers open simultaneously with the beginning of the suction through' the patch-applying member and leave the patch on the under face of the patch-applying member as above pointed out. The opening of the grippers at this point is effected by meansof a projection 73 which strikes against the roller 68 and separates the grippers. The grippers are then carried back to receive another patch and the creasing plunger 26 and the patchapplying member 34' with its attached patch begin their descent to apply the patch to the blank as will now be described.

In the drawings, Figures 4 to 8 inclusive indicate the mode of operation of the creasine' plunger and the patch applying member. In Figure 4 a patch 38 is shown attached to the patch-applying member 34 and resting within the recess 37 on the under face there? of. The gummed blank 74 is shown resting upon the creasing plate 25 and the creasing plunger 26 is descending at a uniform speed with the patch applying member 34 and the patch applying member located over the plunger. In Figure 5 the creasing plunger 26 is shown contacting with the blank 74 and beginning to force the same through the opening 25 in the creasing plate to produce the creasing operation.

At Figure 6 the creasing plunger 26 has forced the creased blank down to the folding bed 27 and has reached the limit of its downward movement. The patch applying member continues its downward movement and passes through the opening 33 in the creasing plunger which opening is so located that the patch applying member can bring its patch into contact with the blank and over the opening 14 therein. When the patch applying member 34 reaches this position, the suction exerted through it to retain the patch on its under face is reversed and acts as an air blast to blow off the patch 38 ontO the face of the blank.

During this operation the creasing plunger 26 acts to hold the blank down on the folding bed 27. After the patch is applied, as shown in Figure 7, the patch-applying member 34 rises, moving out of the opening 33 as disclosed in Figure 8 to its former position above the plunger. then the creasing plunger 36 and the patch-applying member 34 move upward together to their first position disclosed in Figure 1 with the patch applying member 34 in position above the creasing plunger and ready to receive another patch. This cycle of operation is repeated as long as the machine is in operation.

It will be noted that the patch-applying member 34 does not press the patch upon the blank but rather blows the same thereon by an air blast. This form of machine is speedy in operation, prevents the patches from sticking to the patch applying member, and as the patch applying member is recessed on its under face. said face is not brought into contact with the blank and thus the possibility of gum reaching the patch applying member.should a patch tail to adhere thereto.'is avoided.
